Scale-invariant freezing of entanglement
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
We show that bipartite entanglement in a one-dimensional quantum spin model undergoing time-evolution under local Markovian environments can be frozen over time. We demonstrate thi…
Activation of Nonmonogamous Multipartite Quantum States
Saptarshi Roy, Tamoghna Das, Asutosh Kumar +2
The monogamy relation for quantum correlations is not satisfied by all measures for all multiparty quantum states. We prove that an arbitrary quantum state which is nonmonogamous f…
Static and dynamical quantum correlations in phases of an alternating field XY model
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
We investigate the static and dynamical patterns of entanglement in an anisotropic XY model with an alternating transverse magnetic field, which is equivalent to a two-component on…
